Description

[Detailed description of the invention] <Industrial application field> This invention is used to temporarily store and transport grain harvested by large agricultural machines such as combines, and the grain is placed on a truck or the like for transportation. Regarding grain containers, the rear end of the transfer mechanism is connected to the outlet side of the transfer mechanism at the bottom of the storage tank to transport and input grains into rice centers, large dryers, etc. of general farmers. This invention relates to an improvement of a grain container developed to connect the two on different axes in order to improve transfer performance.

<Prior art> Conventionally, in the case of such grain containers, the storage tank was formed into a hopper shape using an iron plate, and the hopper-shaped storage tank was formed into a frame with a planar rectangular shape so that it could be placed on a truck or the like. Generally, it is fixed and supported integrally within the machine frame.

Therefore, conventional grain containers are heavy and have poor transportability when placed on a truck or the like. In addition, since agricultural mechanisms are generally not used throughout the year and are only used temporarily during the harvest season, they are required to be easily stored within buildings, but conventional grain containers are fixed and integrated. Therefore, not only do they require a large storage space, but they also have the disadvantage of being extremely troublesome to transport and store within a building.

<Problems to be solved by the invention> The problems to be solved by the invention are to provide a grain container that is lightweight and compact.

<Means for Solving the Invention> The technical means taken by the present invention to solve the above problem is to form a storage tank with a sheet material for storing grains and having a delivery mechanism extending in one direction at the bottom, This tank is supported and shaped by a machine frame, and the machine frame is formed into a rectangular bottom frame, a support frame connected and erected on the four corners of this bottom frame, and each adjacent support frame. A support frame that is constructed of front and rear, left and right horizontal frames that are removably connected across the upper ends, and that is erected on both sides of a frame member on one side of the bottom frame that is parallel to at least the delivery direction of the delivery mechanism. is made to be tiltable and movable on the one side frame material with its lower end as a fulcrum, and one end side of the two side frame materials on both sides of the bottom frame perpendicular to the sending direction is fixedly connected to the one side frame material. The main feature is that it can be freely moved upright using a fulcrum approximately halfway in the middle.

<Function> According to the above configuration, the support and shape retention of the storage tank is released by removing the front and rear, left and right horizontal frames of the machine frame from between the upper ends of each support frame erected at the four corner corners. The storage tank is placed on one side of the bottom frame bordering the delivery mechanism at the bottom, that is, on the upper side of the bottom frame, which is located on the opposite side from the frame material side of one side of the bottom frame on which the support frame is erected so as to be tiltable. Wrap or fold. Then, two support frames erected on both sides of the other one-side frame member existing in parallel with the one-side frame member of the bottom frame with the storage tank rolled or folded are tilted onto the one-side frame member. , or removed, and then tilting the two support frames that stand upright so that they can be tilted freely, and folding both support frames of the frame members on both sides of the bottom frame perpendicular to the sending direction of the sending mechanism. One end side of the grain container is made to stand upright on its substantially midway point as a fulcrum, thereby making the grain container compact in the height direction and one side width direction, thereby improving storage performance.

The removed horizontal frame and support frame are stored by being rolled up or folded into a storage tank, or sandwiched between them, or sandwiched between the storage tank and the bottom frame for storage.
